>"And there's another 10-20 gallons of various oils in the engine and transmission. While they aren't nearly as volatile as the gasoline, they're still quite flammable"<1. Off by an order of magnitude: ~4-6 quarts of oil in the motor, about the same for the transmission yielding for a large motor about 2 gallons total.
2. duskwuff says >"they're still quite flammable."< Nonsense. Engine oil is so hard to burn that it is not classified as flammable by OSHA:

Furthermore these oils are encased in heavy metal (the engine block, the transmission block and the differential casing).
Starting batteries (the 6- and 12-volt kind) cause more fires than do engine and/or transmission oils.
To paraphrase Charlton Heston: "I'll give you my gasoline car when you can pry it from my cold, greasy, dead hands."
